Product summary

"ISUN - Antioxidant Sun Butter SPF 27" "is a broad spectrum sunscreen meaning that it protects both from UVB rays (" burning "- they cause sunburn) and UVA rays (" aging "- they don't cause sunburn but lead to premature aging and pigmentation issues). However, this moisturizer does not offer enough sun protection. We recommend to use a sunscreen with at least SPF 30 daily.

It also works as a moisturizer, so you do not have to use an additional hydrating product.
